LEROY J. WARNER, OF FOSTORIA, OHIO.

Application filed February 26, 1920.

To all whom it may concern:

Be it known that I, LEROY J. WVARNER, a citizen of the United States,and a resident of F ostoria, in the county of Seneca and State of Ohio,have made an invention appertaining to Inking-Roll Trucks; and I dohereby declare the following to be a full, clear, and exact descriptionofthe invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to the characters of reference markedthereon, which form a part of this specification.

This invention relates to radially expansible rollers and particularlyto a roller of this type adapted for use as an inking roll truck.

The primary object of the invention is the provision of a simple,eflicient and improved roller of the character described which has anexpansible rim that is easily adjustable to increase the diameter of theroller to compensate for wear or for variance in size of the associatedinking roll.

The invention is fully described in the fol lowing specification, andwhile in its broader aspect it is capable of embodiment in numerousforms, a preferred embodiment thereof is illustrated in the accompanyingdrawings, in which,

Figure 1 is a side elevation of the truck applied to one of thetrunnions of an inking roll. Fig. 2 is an end elevation of the truckremoved from the trunnion. Fig. 3 is a sec tion on the line 33 in Fig.2, and Fig. 4: is a section on the line 44 in Fig. 1.

Referring to the drawings, 1 designates an inking roll, 2 an endtrunnion thereof, 3 a truck embodying the invention, and 4 a rail onwhich the truck is intended to travel to maintain the inking surface ofthe roll in proper relation to a form over which it is adapted to passto ink the same.

The truck 3 comprises a sleeve or hub member 5 with one end, in thepresent instance, provided with a radial flange 6 and its other endexternally threaded for a distance lengthwise of the sleeve. Twocollars, 8, 9 are mounted on the sleeve 5 and have their adjacentsurfaces of conical form to provide a groove or space therebetween,which is substantially V-shape in cross-section. The collar 8 abuts atits outer side against the sleeve flange 6 and the other collaris inabutment at its outer side Specification of Letters Patent.

with a nut 10' threaded on the sleeve and adjustable, to effect avarying of the space between the two collars, as is apparent. The nut 10is locked in position by a jam nut 11 threaded on the sleeve therewith.

An annular set of balls 12 are disposed in the space between the collars8, 9 in opposed contact with the conical surfaces thereof and areretained in said space by an expansible band which, in the presentinstance, comprises two split bands 13 and 14 of ring form disposed onewithin the other with the split of each out of register with the other.The purpose of the outer band is to close the split or opening in theinner band when expanded so that there is no possibility of aregistering ball 12 passing therethrough. In order that ,the opening ofthe two bands may be permanently maintained out of register, one of thebands, the outer in the present instance, is provided with a stud l5projecting into the opening of the other band.

The rim member 16 of the truck roller is of cxpansible material,preferably rubber, and closely encircles the bands 13 and 14, beingcarried thereby, with its inner side edges confined between the conicalcollars 8, 9. This provides a rim member for the truck which will notmar the track 4!: in its passage thereover as is frequently the casewith trucks of this character heretofore used.

It is evident that to adjust the truck roller to increase the diameterthereof or to compensate for wear of the peripheral surface thereof, itis only necessary to tighten the nut 10 to effect relative inwardmovement of the collars S, 9. thereby forcing the balls 12 outward inuniform relation by reason of the contact of the conical surfaces of thecollars therewith, and also effecting a corresponding expansion of thebands 13 and 14; and rini LG by reason of the outward movement thereofwith the balls.

It is found in practice that inking rolls when subjected to varyingweather conditions are caused to swell or contract to a greater or lessextent, and it is the primary nirpose of the present invention toprovide an inning roll truck which is easily adjustable to compensatefor any variance in the siez of the roll, for it is evident that shoulda swollen inking roll be run over a form the surface of the roll wouldbe cut and damaged by sharp rulings or projections on the form. Tocompensate therefor it is only necessary to turn the nut 10 the desiredex tent to allow for the swelling of the roll.

I wish it understood that my invention is not limited to any specificconstruction, arrangement or form of the parts, as it is capable ofnumerous modifications and changes without departing from the spirit ofthe claims.

' Having thus described my invention what I claim as new and desire tosecure by Letters Patent, is,

1. An inking roll truck comprising a hub member, a pair of collarsmounted for relative axial movements thereon and having their adjacentsurfaces of opposed conical form, a set of balls encircling the hubmember between the collars in opposed contact with their opposed conicalsurfaces, an expansible band encircling said balls and resting thereon,an expansible rim without the said band, and means cooperating with thehub-member and operable to effect a rela tive axial adjustment of thecollars and'a consequent radial adjustment of the balls, band and rimmembers. 7

2. An inking roll truck comprising opposed collars having theiradj-acent faces of conical form to provide a substantially vshaped'space therebetween, means carrying said collars and adjustable torelatively move the .same to vary the space therebe tween, an annularset of balls disposed in the space between the collars in contact withthe conical surfaces thereof, and an expansible rim member supported bythe balls and expansible by an outward movement of the balls upon arelative inward movement of the collars.

3. An expansible rollers coni arising a pair of collars having adjacentconical faces forming a substantially V-shaped space therebetween, meanscarrying the collars and adjustable to relatively move the collars tovary the space therebetween, an annular set of balls riding on the coni*al fates of the collars, a plurality of split expansible bands disposedone 'within the other and supported by said balls, said bands havingtheir openings out of register, and an pansible rim member externallycarried by said bands In testimony whereof I have hereunto signed myname to this specification.
